Plot 3D Vectors in arrows
Here is a matlab code for creating 3D plots of vectors in terms of arrows. In fact it has been modified to read periodically a number of lines (28 in this case) from the input data file (six columns coorx, coory, coorz, vecx, vecy, vecz) and makes a 3D plot in terms of read arrows. In addition the second half of the code, still within the for loop, is making an animation in gif from all the plots. Enjoy.
